Abstract: | Thirteen field campaigns were undertaken in the period from December 2, 2002 until September 1, 2004 to collect water samples
in order to characterize the quality of rainfall and roof drainage in the city of Xanthi, a typical provincial city in Greece.
In each campaign, water samples were collected from 10 representative sites in the city (in total 130 samples), representing
areas of distinct land use and human activities (i.e., traffic volume, residence density and industrial activity). The water
samples were analyzed according to drinking water criteria for total coliform (not detected), temperature (range: 0.9–20°C),
pH (range: 3.6–11.4), alkalinity (range: 0–21.5 mg CaCO3/L), nitrate (range: 0–2456 μg/L), ammonium (range: 0–2628 μg/L), sulfate (range: 0–0.5 mg/L), calcium (range: 259.1–3064
μeq/L), magnesium (range: 0.8–488.8 μeq/L), potassium (range: 0.0–110.6 μeq/L) and dissolved heavy metals (Fe, range: 0.01–0.18
mg/L; Mn, range: 0.01–0.09 mg/L; Zn, range: 0.01–0.54 mg/L; Cu, Cr and Ni, not detected). Pollutant concentrations were generally
higher in roof drainage than in rainwater, but both were lower than drinking water standards. Dissolved heavy metal concentrations
were generally higher in the areas of intensive human activities, such as roads with high traffic volume and densely populated
residential areas. The satisfactory quality of rainwater, which results from this analysis, makes its use as grey water possible. |
